dangerous

 
  1. How to be a dangerous person. Strongest man in the world. The imagination of the audience is what makes somebody dangerous. The person can not play dangerous. Schindler's List example.
  2. What makes them dangerous: they don't act dangerous, no yelling etc. Wrong: (both didn't have smooth look).
  3. When playing dangerous person, don't. Murder doesn't play murderer.

"In the end, it can't look like acting."
